+Device Tree Clock bindings for arch-sunxi
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be one of the following:
+	"allwinner,sunxi-osc-clk" - for a gatable oscillator
+	"allwinner,sunxi-pll1-clk" - for the main PLL clock
+	"allwinner,sunxi-cpu-clk" - for the CPU multiplexer clock
+	"allwinner,sunxi-axi-clk" - for the sunxi AXI clock
+	"allwinner,sunxi-ahb-clk" - for the sunxi AHB clock
+	"allwinner,sunxi-apb0-clk" - for the sunxi APB0 clock
+	"allwinner,sunxi-apb1-clk" - for the sunxi APB1 clock
+	"allwinner,sunxi-apb1-mux-clk" - for the sunxi APB1 clock muxing
+
+Required properties for all clocks:
+- reg : shall be the control register address for the clock.
+- clocks : shall be the input parent clock(s) phandle for the clock
+- #clock-cells : from common clock binding; shall be set to 0.
+
+For example:
+
+osc24M: osc24M@01c20050 {
+	#clock-cells = <0>;
+	compatible = "allwinner,sunxi-osc-clk";
+	reg = <0x01c20050 0x4>;
+	clocks = <&osc24M_fixed>;
+};
+
+pll1: pll1@01c20000 {
+	#clock-cells = <0>;
+	compatible = "allwinner,sunxi-pll1-clk";
+	reg = <0x01c20000 0x4>;
+	clocks = <&osc24M>;
+};
+
+cpu: cpu@01c20054 {
+	#clock-cells = <0>;
+	compatible = "allwinner,sunxi-cpu-clk";
+	reg = <0x01c20054 0x4>;
+	clocks = <&osc32k>, <&osc24M>, <&pll1>;
